My god, you really don't understand this most basic pont. You have to know all the infinite digits to the right of the decimal to know it's all '9', in other words, it's infinite precision. To say 'if it's not all nines, it not equal to one. It's not hard' and not understand you have to know all infinity of them to determine this.
or see wiki:
A real number may be either rational or irrational; either algebraic or transcendental; and either positive, negative, or zero. Real numbers are used to measure continuous quantities. They may be expressed by decimal representations that have an infinite sequence of digits to the right of the decimal point; these are often represented in the same form as 324.823122147… The ellipsis (three dots) indicates that there would still be more digits to come.
This is so obvious, I can only think you have some block where you don't understand the question.
